A code segment that is given a name and is used to perform a specific task. One result is returned as a function designator. The syntax is similar to a program. A function can have local declaration and a body. A statement assigning the result to the function designator should be at the end of the function body.
A relationship between two or more variables, usually expressed by means of an equation. The variables which are free to take on values are called independent variables. The variables which are determined by the function are called the dependent variables.
A stored program, written in PL/SQL, stored in a database. It must return a value.
Any defined procedure that relates one number, quantity, etc., to one or more others. In algebra, a function of the variable is often written f(x).
A built-in element of code that return a value.
In BASIC, a token that when executed returns a value to the program.
HLU: Any member of the NCL functions or the HLU API. NCL: An identifier with a list of parameters separated by commas and enclosed in parentheses. Functions return values when called. A function is defined by NCL source unlike the NCL intrinsic function.
y = f(x) the set of all ordered pairs (x,y) with x belonging to the domain X and y belonging to the range Y. No two pairs have the same x-value.
n. An undefined measure of the value of a program or machine, in the sense of describing what it is able to achieve.
(Korn/Bash) keyword to define a function enabling local variables.
A procedure returning a value assigned to a variable.
procedure that returns a value (the function result) and that can be referenced in an expression.
An operation that computes and returns a result without observable side effects.
A function is a scalar function defined by the : command. Its value is not determined at the point where the : command is used. Instead, the functional form is stored and evaluated therafter when called. Depending upon the arguments to the function at at a given time, the evaluation may change.
function is a subclass of class code which yields a value when executed. The most important functions are local variables ( var), obtainers and mathetical operations. They may be used as arguments to code objects. They are executed when the code object is executed or when the function needs to be converted to a type that does not accept a function.
procedure that returns a value. A function to return the interest on a bank account would be better practice than a procedure which put the value into a global variable. Back to where you were
A relationship in which every value of x has a unique value of y (e.g., the relation y = 2x + 1 is a function because for every different x, there is one and only one y).
A predefined XPath expression that returns a value based on the results of a calculation.
A set of SQL or PL/SQL statements used together to execute a particular function. Procedures and functions are identical except that functions always return a value (procedures do not). By processing the SQL code on the database server, you can reduce the number of instructions sent across the network and returned from the SQL statements.
A block of code that gets called, executes, then returns control (and, optionally, a value) to the caller
A relation in which each value of an independent variable takes on a unique value of the dependent value.
A subprogram which returns a value to its point of invocation.
A routine that can accept arguments and returns one or more values. See also built-in function, routine, user-defined function.
A general term used for a subroutine. In some programming languages, a subroutine or statement that returns values.
A relation that associates each object in a set with exactly one value.
A relation in which every input value has a unique output value.
An object used for performing actions and returning values. Functions have a parameter list and an optional return value declaration, which together define the function's signature. There are two kinds of functions: method and generic function. A method has a body of code that is executed to compute the method's values when the method is called. A generic function consists of a set of methods, and computes its values by selecting and calling an appropriate method based on the types of the arguments.
A procedure that returns a value (unlike a sub which does not return a value)
with independent variable and dependent variable : exactly one for each .
A set of instructions that is given a name. In general, a function returns an object and may be provided with data (arguments) when it is called (used). The arguments are used to initialize the function's parameters.
A procedure that returns a value. Compare with subroutine.
A procedure that returns the value of a single variable and that usually has a single exit.
In WebDB, PL/SQL subprograms that perform a specified sequence of actions, and then return a value. In WebDB sites, a PL/SQL procedure or user function that returns a value. End users can execute procedures or functions in a WebDB site by clicking on the title of a PL/SQL or custom item. Functions are usually small, very specific blocks of code written to perform a specific task within the scope of a larger application.
In Fortran, a procedure that is invoked by referring to it in an expression and that supplies a value to the expression. The value supplied is the value of the function. See also external function, intrinsic function, and statement function. Contrast with subroutine.
A function is a relation between variables and such that each value of corresponds to only one value of . (See also polynomial and variable.) Examples: = sin is called the independent variable and as a function of , is called the dependent variable. The set of all the values that makes the function meaningful is called the domain and the set of all the possible values of the function is called the range. Thus, the domain of +1 is the real line and the range of +1 is the real line. The domain of = sin is all real except = 0 and the range is -1
A function is a section of code, in a program, that sets up for an action upon a set of arguments, and produces an output, but which does not take its defined action until it is called.
prototype: Information for the compiler and user about how to use a function. Gives function name, return type, a parameter list (number and type of arguments in order)
a computer subroutine; a subroutine that performs a calculation with variables provided by a program and supplies the program with a single result
a relation in which each value of x is paired with a unique value of y.
When metrics are a function of drivers then each value of a metric will have one corresponding set of driver values.
A function f of a variable x is a rule that assigns to each number x in the function's domain a single number f(x). The word "single" in this definition is very important
subprogram which returns a value of a specified type which is invoked as part of an expression.
Mathematics: A mathematical expression describing the relation between variables; the function taking on a definite value, or values, when special values are assigned to certain other quantities, called the parameters, or independent variables of the function. Computer Programming: Any procedure that performs a predefined operation and that returns some type of result as an output. The output can be a number, a text string, or a logical response, such as true or false. Most functions require inputs, known as arguments. The outputs of those functions requiring inputs is determined by evaluating the inputs presented. A few functions, such as those that return the current date or time of day, obtain their inputs internally from the system clock or some other source and do not require other inputs.
The term used in this manual to describe C procedures and functions, and Fortran functions and subroutines.
ISO] A mathematical entity whose value, namely, the value of the dependent variable, depends in a specified manner on the values of one or more independent variables, with not more than one value of the dependent variable corresponding to each permissible combination of values from the respective ranges of the independent variables. A specific purpose of an entity, or its characteristic action.
An automatic procedure that accepts one or more variables or values as input and returns a value (text, numeric, or logical) as a result.
In Visual Basic, a type of subroutine that can accept an argument and returns a value assigned to the function as though it was a variable. You can code your own functions or use builtin functions provided by Visual Basic. For example, in this example, both Now and MsgBox are functions. Now returns the system time. MsgBox(Now)
Pre-established formula where you supply the information (called arguments) needed to make the calculation. Excel has 200 built-in functions.
A logical object which accepts one or more inputs (arguments) and produces a single output (value) uniquely determined by the combination of the input and the formal specification of the function.
A relationship between two sets of values, where the second value (the "output") is uniquely determined (according to some clearly specified "rule") by the first value (the "input").
A body of code that can be called by other code or by itself, or a variable that refers to the function. When a function is called, arguments are passed to the function as input, and the function can optionally return an output. A function is also an object. See Functions.
A set of software instructions that returns a value when executed. e.g. Y= COS(x)
A PL/SQL stored procedure that can define business rules, perform automated tasks within an application, or retrieve application information. The stored procedure accepts standard arguments and returns a completion result.
A procedure, beginning with Function functionname() and ending with End Function, that returns a value to the calling procedure when it's complete.
A predefined operation that returns a single value.
Something which determines for each of a number of possible values for arguments (to the function) a specific value which is the result of the function for that argument. (in set theory) a many-one relation (which is sometimes called the graph of the function) (in computing or constructive mathematics) an expression or rule which shows how the value of a function may be computed, or is otherwise determined by, the value of the argument to the function.
A block that is invoked with a function call and returns a value.
A correspondence in which values of one variable determine the values of another.
1. an object representing code, which can be called with zero or more arguments, and which produces zero or more values. 2. an object of type function.
A sections of code that can be called from other code. In C you must declare the function before any code that calls it (or get a warning) and define the function somewhere in the code (or get an error). Functions take inputs called arguments that can change how they work internally. Functions have an associated block of code called the function body that defines the code that the function does. Functions can return a value of any type to the code that calls it. Note that functions have a distinction between declaration and definition, whereas a variable has none; declaration and definition are identical.
A mathematical relationship between two variables, sets of numbers, or an independent variable and a dependent variable. Every value of the independent variable corresponds to exactly one value of the dependent value. Functions can be used to understand how one quantity varies in relation to (is a function of) changes in the second quantity. For example, there is a functional relationship between the price per pound of a particular type of meat and the total amount paid for ten pounds of that type of meat. You can see that values of one variable determine the values of another.
A mathematical relationship between two values called the input and the output, such that for each input there is precisely one output.
